 Differential reinforcement is when we reinforce a behavior, but not another one Doesn't make sense, right? So you're like, what are you talking about dude? How many of you ever tried it to weld with a stick welder going so if the stick sticking out here and you well I don't know if you can see this. Maybe you can so you go. I think I did it wrong I think you're supposed to go All right, so differential reinforcement if you weld one way right with a stick welder if you pull it or push it You're gonna get different effects and it's gonna happen it one way is gonna produce a hot Well one way is gonna produce a cold well one way is gonna put a whole bunch of material in there when you may or may not want it And then to make matters even worse switch yourself over to a big welder or a TIG welder And you gotta do everything differently Well in order to produce the reinforcers of having an effective nice penetrating weld that's strong Then you have to change your procedure You're differentially reinforced if I engage in this behavior doing this direction It's gonna produce reinforcers if I do it the other way it's not differential reinforcement So back to shaping differential reinforcement is what you use it. This is the behavior we want at this time We're going to change that to a different response and reinforce that one next time differential reinforcement
